Organization: ISO
Publication Date: 1 March 2021
Status: active
Page Count: 38
ICS Code (Air quality in general): 13.040.01
ICS Code (Radiation measurements): 17.240
scope:

This document describes radon-222 integrated measurement techniques with passive sampling. It gives indications for determining the average activity concentration of the radon-222 in the air from measurements based on easy-to-use and low-cost passive sampling, and the conditions of use for the sensors.

This document covers samples taken without interruption over periods varying from a few days to one year.

This measurement method is applicable to air samples with radon activity concentrations greater than 5 Bq/m3.
